Focus on the Total renewable water resources per capita.

 

 Renewable water resources represent the long term average annual flow of rivers (surface water) and the recharge of aquifers (groundwater) generated by a country’s precipitation. That is, the water available for the population and productive activities in a country. At the per capita level, global freshwater availability in 2022 was estimated at 5 326 m3 per capita: a 7 percent decrease compared to 2015, when total renewable water resources stood at 5 719 m3 per capita (Figure 2). At the regional level, Northern Africa had the lowest freshwater resources per capita in 2022 with an estimated amount of 565 m3 per inhabitant, followed by Southern Asia (1 226 m3 per capita) and Western Asia (1 252 m3 per capita). The rest of the regions had 1 700 m3 per capita or more in the same year. Since 2015, all world regions experienced a decline in per capita availability of renewable water resources. Sub-Saharan Africa recorded the largest decrease, at 17 percent, followed by Central Asia (12 percent), Northern Africa (12 percent), Western Asia (11 percent) and Oceania (9.84 percent).
